Abstract
A method for recovering cyclodextrin, comprising passing an aqueous solution containing an inclusion compound of cyclodextrin with a guest compound, through a non-polar, high-porous hydrophobic adsorption resin, which is the cross-linked copolymer of styrene with divinylbenzene, comprised of styrene as a basic skeleton, to cause the adsorption resin to preferentially adsorb the guest compound for its removal. The method enables economical recovery of cyclodextrin in a good efficiency and at a high purity from inclusion compounds of cyclodextrin with guest compounds such as cholesterol and other lipids.
